I think that they would do anything to break them up and if draco still want that muggle born they will disown him for sure,especially Lucius,Narcissa may forgive him because he is her beloved son,but for sure she would never accept her daughter-in-law,she just would want to be in good terms with her son!!!Lucius would sure have a heart attack if Draco would marry a mudblood XD!!!!

I think so.

Lucius would kill the muggleborn.

most possible of these

Personally, I think both would accept her eventually just to be in good terms with Draco.
I think they love him too much to put their views ahead of his happiness.

More or less....

lmao pretty much.

lucius would probably have a heart attack lmao, and then kill the muggleborn

^ hahah i agree

No doubt made by a Dramione fanatic. First of all, no way would Draco ever, EVER, marry a muggleborn. He hates them just as much as his heritage and has grown up that way. I doubt even Narcissa would be too accepting.

Narcissa would never turn her back on Draco though, no matter what. Despite how prejudiced she is, he is her beloved son and she loves him - and Lucius - more than anything in the world. After all, she turned her back on Voldemort to make sure Draco was safe and well.
And this is why I believe Lucius wouldn't abandon him either. Despite not being the world's best father - he brought up his son to share his own prejudice and didn't consider his safety when he pledged his allegiance to Voldemort and joined the Death Eaters. But Lucius, like Narcissa, put Draco above their Master, Lord Voldemort, and I do believe he cared about him. This is the most possible pick, but either way it's irrelevant as I don't think there's any chance of Draco, with the strong sense of prejudice instilled in him, would marry a Muggleborn. It's just the way he was raised, even though I do think he may have reconsidered quite a bit after the Battle of Hogwarts - the small, respectful nod to the Trio on Platform 9 and 3/4 in the Epilogue said it all.
